Biography
Magnus Haakonsson was the youngest son of Haakon Haakonsson and his wife Margaret Skuladotter, born in Tunsberg in 1250. In 1261 he was married to the Princess of Denmark, Ingeborg Eriksdotter, to consolidate a trans-Scandinavian alliance. Magnus accompanied his father on the invasion of Scotland in 1268, at the age of 18, and upon his father's death in 1276, he became the King of the Kingdom of the Isles. Magnus VI of Norway, as he became known, was the first king of Norway to be known by an ordinal number, and he was also the first to define the border with Sweden.

King Magnus proceeded to fight the Scots for the control of the island of Mull, and in 1281 King Alexander III of Scotland besieged Mull. Magnus was killed in the Scottish assault on the city, and the Kingdom of the Isles, leaderless, turned into fragmented rebel states.
